Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is revered for its versatility and cost-effectiveness compared to other high-performance ceramics. It is distinguished by its exceptional electrical insulation resistance, remarkable durability under high temperatures, incredible hardness, wear resistance, and superb chemical stability, making it the definitive choice for withstanding extreme temperatures and aggressive chemical environments.
Within our state-of-the-art facility, we produce alumina parts of outstanding purity levels, ranging from 75% to a distinguished 99.8%. Each ceramic component is intricately crafted using advanced techniques like dry pressing, hot pressing, ceramic injection molding, and ISO pressing. We cater to specialized needs involving fitting, friction reduction, and enhanced insulation, providing post-sintering secondary processes such as CNC machining, polishing, glazing, and metalizing.
We take pride in manufacturing an extensive range of alumina ceramic components, including ceramic tubes, rings, discs, rods, arms, and wire guides. Whether your endeavor entails prototyping or expansive production, we deliver unmatched expertise to custom-tailor solutions to meet your exact specifications.
